Common questions
- What hardware do I need?
- Any standard Bluetooth LE OBD-II adapter (commonly around $20). There is no proprietary
hardware and nothing is locked to us — an adapter you already own will usually work.
- The app can't find my adapter.
- Turn the ignition on, make sure the adapter is seated firmly in the OBD-II port, and confirm
Bluetooth is enabled for Root Cause Mechanic in iOS Settings. Some adapters need to be paired
in the app rather than in iOS Bluetooth settings.
- Can I try it without an adapter?
- Yes. The showroom vehicle replays a real, documented case end to end, so you can see how a
diagnosis is reached before buying anything.
- How do I delete my account?
- In the app: Settings → Delete Account. This permanently removes your account
and all associated data — vehicles, case history, drives, and evidence. It cannot be undone.
- Is my data shared or sold?
- No. Your vehicle data is yours. We do not sell it, share it with data brokers, or use it for
advertising. See our Privacy Policy.
- Does the app tell me what to repair?
- It gives you evidence and a ranked explanation of what the data supports, plus what it rules
out. It is a second opinion to help you ask better questions — it does not replace a
qualified mechanic's inspection.
